Dell laptop c640 s-video port usage


Normally you have to use Fn(function key) on your keyboard + F4 key (F4 or maybe some other key you have to see and icon on your F4,F10 key..it should look like a a monitor icon) try it.
Press Fn first and hold it and press F4....
The first time it should output only to your S-video,second pressing it should output both s-video and your monitor.
goodluck,takecare.

This is a rather old question, but the solution might still be helpful to other readers.

I suggest you call Tech Support at Dell...

Several years ago, I worked on many Dell CPx 500 models in my work place. There was an issue that always involved a series of 4 or 5 keys (they were always the same keys) that would quit working and we had attempted to purchase new keyboards to fix the issue. It turned out, the real solution was to replace the 'motherboard' of the Latitude notebook!

Dell had knowledge about the keyboard/motherboard issue that we didn't know.
